Beberapa aplikasi berbasis web yang memakai Java tidak dapat jalan jika memakai OpenJDK, sehingga harus memasang Sun JDK atau JRE.

Unduh Sun JDK atau JRE

Unduh Sun JDK atau JRE versi 7 dari http://java.sun.com/javase/downloads/index.jsp

Unduh berkas rpm

  • jre-7u10-linux-i586.rpm
  • jdk-7u10-linux-i586.rpm

Pasang Sun JDK atau JRE

Pasang salah satu: 

# rpm -ivh jre-7u10-linux-i586.rpm

atau 

# rpm -ivh jdk-7u10-linux-i586.rpm

Ubah ke Sun JRE

Jika sebelumnya telah memasang OpenJDK, maka sistem harus diubah agar memakai Sun JDK, lakukan: 

## java ##
# alternatives --install /usr/bin/java java /usr/java/latest/jre/bin/java 20000

## javaws ##
# alternatives --install /usr/bin/javaws javaws /usr/java/latest/jre/bin/javaws 20000

## Java Browser (Mozilla) Plugin 32-bit ##
# alternatives --install /usr/lib/mozilla/plugins/libjavaplugin.so libjavaplugin.so /usr/java/latest/jre/lib/i386/libnpjp2.so 20000

## Pasang javac hanya jika memasang Java Development Kit (JDK)
# alternatives --install /usr/bin/javac javac /usr/java/latest/bin/javac 20000
# alternatives --install /usr/bin/jar jar /usr/java/latest/bin/jar 20000

Mengatur path ke JDK

Setelah instalasi lakukan pengaturan variabel JAVA_HOME ke /etc/profile atau ke $HOME/.bash_profile

Gunakan Java JDK dan JRE versi terakhir (/usr/java/latest) 

## export JAVA_HOME JDK/JRE ##
export JAVA_HOME="/usr/java/latest"
